本發明係關於具備沿著第1方向排列的複數個電極和沿著第2方向排列的複數個電極之觸控感測器用電極、觸控面板及顯示裝置。 The present invention relates to a touch sensor electrode, a touch panel, and a display device including a plurality of electrodes arranged along a first direction and a plurality of electrodes arranged along a second direction.
搭載於顯示裝置或攜帶終端的觸控面板具有:沿著一方向之X方向延伸的複數個第1電極、和沿著與X方向正交的Y方向延伸的複數個第2電極。複數個第1電極係與複數個第2電極呈立體交叉,具有單層構造或多層構造的透明介電體層位在此等複數個第1電極與複數個第2電極之間。而藉由檢測複數個第1電極中的任一個第1電極和複數個第2電極中的任一個第2電極之間的靜電電容的變化,來判定對觸控面板的輸入位置。 A touch panel mounted on a display device or a portable terminal includes a plurality of first electrodes extending along the X direction in one direction and a plurality of second electrodes extending along the Y direction orthogonal to the X direction. The plurality of first electrode systems are three-dimensionally intersected with the plurality of second electrodes, and a transparent dielectric layer having a single-layer structure or a multi-layer structure is located between the plurality of first electrodes and the plurality of second electrodes. An input position to the touch panel is determined by detecting a change in electrostatic capacitance between any one of the plurality of first electrodes and any one of the plurality of second electrodes.
提高觸控面板之位置的檢測精確度的要求,係隨著對於觸控面板之輸入形態的多樣化或搭載觸控面板之顯示裝置的高解析度化而持續升高。因應此種要求之一提案的第1電極具備有:具有菱形形狀且沿著X方向排列的複數個第1電容電極部;和具有比第1電容電極部還小的大小並且連接相互相鄰的第1電容電極部之間之第1連接部。又,第2電極具備有:具有菱形形狀 且沿著Y方向排列的複數個第2電容電極部;和具有比第2電容電極部還小的大小並且連接相互相鄰的第2電容電極部之間之第2連接部。由透明介電體層的表面觀看,是以第1連接部和第2連接部彼此重疊,另一方面第1電容電極部和第2電容電極部彼此不重疊之方式,配置第1電極和第2電極(例如,參照專利文獻1)。 The requirements for improving the detection accuracy of the position of the touch panel continue to increase with the diversification of the input form of the touch panel or the high resolution of the display device equipped with the touch panel.

具有上述之電容電極部的觸控面板,藉由使第1電容電極部和第2電容電極部從透明介電體層的表面觀看不會重疊,提高了位置的檢測精確度。另一方面,由於透明介電體層位在第1電極和第2電極之間,所以即便電極本身是由相同的材料所形成,但既然在兩個電極之間存在透明介電體層,第1電極的電容電極部所具有的顏色和第2電極的電容電極部所具有的顏色從透明介電體層的表面觀看也會相差很多。結果,使得第1電極和第2電極被辨識為各別的構造體。尤其,在形成第1電極的材料和形成第2電極的材料為彼此不同的構成時,或者在第1電極的表面狀態和第2電極的表面狀態相異時,此等第1電極和第2電極的交界會變得更容易被辨識。 The touch panel having the above-mentioned capacitor electrode portion does not overlap when viewed from the surface of the transparent dielectric layer by the first capacitor electrode portion and the second capacitor electrode portion, thereby improving the accuracy of position detection. On the other hand, since the transparent dielectric layer is located between the first electrode and the second electrode, even if the electrodes themselves are formed of the same material, since a transparent dielectric layer exists between the two electrodes, the first electrode The color of the capacitor electrode portion of the second electrode and the color of the capacitor electrode portion of the second electrode are also significantly different when viewed from the surface of the transparent dielectric layer. As a result, the first electrode and the second electrode are identified as separate structures. In particular, when the material forming the first electrode and the material forming the second electrode are different from each other, or when the surface state of the first electrode and the surface state of the second electrode are different, the first electrode and the second electrode are different. The junction of the electrodes becomes easier to identify.
本發明之目的在提供一種可抑制位置的檢測精確度降低,且可抑制第1電極和第2電極被辨識為各別的構造體之觸控感測器用電極、觸控面板及顯示裝置。 An object of the present invention is to provide an electrode for a touch sensor, a touch panel, and a display device that can suppress a decrease in the detection accuracy of a position and can prevent the first electrode and the second electrode from being recognized as separate structures.

The second direction intersecting with the first direction is arranged on the first surface; the plurality of second electrodes are arranged on the second surface along the first direction; the first dummy section includes a plurality of first virtual lines; and The second dummy section includes a plurality of second dummy lines. Each of the first electrodes is a collection of a plurality of first electrode lines, and includes a plurality of first capacitor electrode portions arranged along the first direction and a first connection portion that connects the first capacitor electrode portions adjacent to each other. Each of the second electrodes is a collection of a plurality of second electrode lines, and has a plurality of second capacitor electrode portions arranged along the second direction and a second connection connecting the second capacitor electrode portions adjacent to each other. unit. The first dummy part is located between the two first electrodes adjacent to each other in the first surface, and is separated from the first electrode. The second dummy portion is located between the two second electrodes adjacent to each other in the second surface, and is separated from the second electrode. In a plan view facing the transparent dielectric substrate, the first capacitor electrode portion is opposed to the second dummy portion, and the second capacitor electrode portion is opposed to the first dummy portion. In the foregoing plan view, a combination of the first electrode line and the second virtual line constitutes a first portion of a grid pattern, and the first electrode line and the second virtual line constitute The mutually different line segments included in the aforementioned lattice pattern. In the aforementioned plan view, the combination of the second electrode line and the first virtual line constitutes a second part of the lattice pattern, and the second electrode line and the first virtual line constitute each other included in the lattice pattern. Distinct line segments.
觸控面板的一態樣係具備:觸控感測器用電極,其係上述觸控感測器用電極,具有複數個前述第1電極、複數個前述第2電極、和挾持於複數個前述第1電極和複數個前述第2電極之間的透明介電體層;覆蓋前述觸控感測器用電極的覆蓋層;及測定前述第2電極和前述第2電極之間的靜電電容之週邊電路。 One aspect of the touch panel includes: a touch sensor electrode, which is the touch sensor electrode, and includes a plurality of the first electrodes, a plurality of the second electrodes, and a plurality of the first electrodes held in the plurality of the first electrodes. A transparent dielectric layer between the electrode and the plurality of second electrodes; a cover layer covering the touch sensor electrode; and a peripheral circuit for measuring an electrostatic capacitance between the second electrode and the second electrode.

根據上述態樣,在面對透明介電體基板的平面視圖中,由於第1電極線和第2虛擬線的組合形成一個格子圖案,且第2電極線和第1虛擬線的組合形成一個格子圖案,所以,第1電極所具有的顏色和第2電極所具有的顏色難以被個別地辨識。因此,即便第1電極所具有的顏色和第2電極所具有的顏色彼此相異,第1電極的顏色和第2電極的顏色之差異也不易引人注目。結果,會抑制第1電極及第2電極的交界被辨識,,且會抑制第1電極和第2電極被辨識。 According to the above aspect, in a plan view facing the transparent dielectric substrate, a combination of the first electrode line and the second dummy line forms a grid pattern, and the combination of the second electrode line and the first dummy line forms a grid. Pattern, it is difficult to distinguish the color of the first electrode and the color of the second electrode individually. Therefore, even if the color of the first electrode and the color of the second electrode are different from each other, the difference between the color of the first electrode and the color of the second electrode is not easily noticeable. As a result, the boundary between the first electrode and the second electrode is suppressed from being recognized, and the first electrode and the second electrode are prevented from being recognized.
且,在第1電極和第2電極中,在與透明介電體基板對向的平面視圖中於沒有相互重疊的第1電容電極部和第2電容電極部之間形成靜電電容。第1電容電極部和第2電容電極部之間的電容部分為容易受到來自透明介電體基板的外側之電氣的影響的部分,所以當導電體靠近觸控感測器用電極時,第1電容電極部和第2電容電極部之間的靜電電容容易改變。因此,檢測導電體相對於觸控感測器用電極的位置之精確度會提高。 In the first electrode and the second electrode, an electrostatic capacitance is formed between the first capacitor electrode portion and the second capacitor electrode portion which do not overlap each other in a plan view facing the transparent dielectric substrate. The capacitance portion between the first capacitance electrode portion and the second capacitance electrode portion is a portion that is susceptible to electrical influence from the outside of the transparent dielectric substrate. Therefore, when the conductive body approaches the electrode for the touch sensor, the first capacitance The capacitance between the electrode portion and the second capacitance electrode portion is easily changed. Therefore, the accuracy of detecting the position of the conductive body relative to the electrode for the touch sensor is improved.

The orthogonal direction extends and has the same length as the length of one side of the aforementioned unit lattice. Preferably, in the first electrode line, the reference direction is the second direction, and a plurality of the reference pattern elements are arranged along the first direction; more preferably, in the second virtual line, the reference direction is In the first direction, a plurality of the reference pattern elements are arranged in the second direction.

另一方面,構成驅動電容電極部31DPa的驅動電極線41中,與位於第2方向D2的中央的3條驅動電極線41不同的6條驅動電極線41具有以下的構成。 On the other hand, among the driving electrode lines 41 constituting the driving capacitor electrode portion 31DPa, six driving electrode lines 41 different from the three driving electrode lines 41 located at the center of the second direction D2 have the following configuration.
在6條驅動電極線41中,愈遠離驅動電容電極部31DPa之第2方向D2的中央者,其沿第1方向D1的長度就愈小。且,6條驅動電極線41的每一者,其沿第1方向D1的長度是以在第1方向D1的兩端相同長度的程度小於位在中央之驅動電極線的長度41。因此,在驅動電容電極部31DPa中,由各驅動電極線41的端部所構成之驅動電容電極部31DPa的外形形狀為六角形形狀。 Of the six driving electrode lines 41, the further away from the center of the second direction D2 of the driving capacitor electrode portion 31DPa, the smaller the length along the first direction D1. In addition, the length of each of the six driving electrode lines 41 in the first direction D1 is smaller than the length 41 of the driving electrode line in the center by the same length at both ends of the first direction D1. Therefore, in the driving capacitor electrode portion 31DPa, the outer shape of the driving capacitor electrode portion 31DPa formed by the end portion of each driving electrode line 41 is a hexagonal shape.
相對地,在構成驅動連接部31DPb的3條驅動電極線41中,沿第1方向D1的長度與沿3條驅動電極線41之第2方向D2的合計寬度係大致相等。 In contrast, among the three driving electrode lines 41 constituting the driving connection portion 31DPb, the length in the first direction D1 and the total width in the second direction D2 of the three driving electrode lines 41 are substantially equal.
驅動虛擬部31DD係位在第2方向D2上相互相鄰的兩個驅動電極31DP之間。驅動虛擬部31DD係位在一方的驅動電極31DP中連續的兩個驅動電容電極部31DPa、和另一方的驅動電極31DP中連續的兩個驅動電容電極部31DPa之間。 The driving dummy portion 31DD is located between two driving electrodes 31DP adjacent to each other in the second direction D2. The driving dummy portion 31DD is located between two consecutive driving capacitor electrode portions 31DPa in one driving electrode 31DP and two consecutive driving capacitor electrode portions 31DPa in the other driving electrode 31DP.
驅動虛擬部31DD包含例如沿第2方向D2隔著等間隔排列的6條驅動虛擬線42,各驅動虛擬線42沿第1方向D1延伸。各驅動虛擬線42包含具有以第2方向D2為基準而制定的圖案形狀之複數個基準圖案要素31RP。 The driving dummy section 31DD includes, for example, six driving dummy lines 42 arranged at regular intervals in the second direction D2, and each driving dummy line 42 extends in the first direction D1. Each driving virtual line 42 includes a plurality of reference pattern elements 31RP having a pattern shape determined based on the second direction D2.
6條驅動虛擬線42中,沿第1方向D1的寬度,是以位在第2方向D2的中央之2條驅動虛擬線42為最大,隨著接近驅動虛擬部31DD之第2方向D2的兩端的各個而逐漸變小。夾著位在第2方向D2的中央之2條驅動虛擬線42而設置的2條驅動虛擬線42,且是位在與第2方向D2的中央隔著相等距離的部位之2條驅動虛擬線42,其沿第1方向D1的長度彼此相等。又,與位在第2方向D2的中央之2條驅動虛擬線42不同的4條驅動虛擬線42中,其沿第1方向D1的長度是以在第1方向D1的兩端相同長度的程度小於位在中央的驅動虛擬線42。 Of the six driving virtual lines 42, the width along the first direction D1 is the largest of the two driving virtual lines 42 located in the center of the second direction D2. Each end gradually becomes smaller. The two driving virtual lines 42 provided between the two driving virtual lines 42 located at the center of the second direction D2 are two driving virtual lines located at a distance equal to the center of the second direction D2. 42. The lengths along the first direction D1 are equal to each other. In addition, in the four driving virtual lines 42 which are different from the two driving virtual lines 42 located in the center of the second direction D2, the length along the first direction D1 is about the same length at both ends of the first direction D1 Less than the driving virtual line 42 in the center.
因此,在驅動虛擬部31DD中,由各驅動虛擬線42的端部所構成之驅動虛擬部31DD的外形形狀為六角形形狀。 Therefore, in the driving dummy portion 31DD, the outer shape of the driving dummy portion 31DD constituted by the ends of the driving dummy lines 42 is a hexagonal shape.
包含於一個驅動虛擬部31DD的驅動虛擬線42中,位於第2方向D2的中央之驅動虛擬線42的一方具有複數個虛擬內間隙42a,複數個虛擬內間隙42a係沿第1方向D1隔著相等間隔排列。複數個虛擬內間隙42a係沿第1方向D1及第2方向D2位在各驅動虛擬部31DD。 Among the driving virtual lines 42 included in one driving virtual portion 31DD, one of the driving virtual lines 42 located at the center of the second direction D2 has a plurality of virtual inner gaps 42a, and the plurality of virtual inner gaps 42a are separated along the first direction D1. Equally spaced. The plurality of virtual inner gaps 42a are located in the respective driving dummy portions 31DD along the first direction D1 and the second direction D2.
在第1方向D1上,驅動虛擬部31DD和驅動電容電極部31DPa的一部分係交互連續地排列。在驅動面31S的一部分中,於第1方向D1上,構成驅動虛擬部31DD的驅動虛擬線42和構成驅動電容電極部31DPa的驅動電極線41係交互連續地排列。在第1方向 D1上交互連續的複數條驅動電極線41和複數條驅動虛擬線42係構成一個驅動圖案群43,在第1方向D1相互相鄰的驅動電極線41和驅動虛擬線42係分別包含共用的一個基準圖案要素31RP的一部分。 In the first direction D1, a part of the driving dummy portion 31DD and the driving capacitor electrode portion 31DPa are alternately and continuously arranged. In a part of the driving surface 31S, in the first direction D1, the driving dummy lines 42 constituting the driving dummy portion 31DD and the driving electrode lines 41 constituting the driving capacitor electrode portion 31DPa are alternately and continuously arranged. In 1st direction The plurality of driving electrode lines 41 and the plurality of driving virtual lines 42 which are continuous and continuous on D1 constitute a driving pattern group 43. The driving electrode lines 41 and the driving virtual lines 42 adjacent to each other in the first direction D1 each include a common one. A part of the reference pattern element 31RP.
在驅動圖案群43中,驅動間隙44係位在第1方向D1之驅動電極線41的端部和驅動虛擬線42的端部之間。驅動間隙44係使驅動電極線41和驅動虛擬線42相互分離。藉此,驅動虛擬部31DD會自驅動電極31DP分離。換言之,驅動虛擬線42會與驅動電極31DP電性絕緣。 In the driving pattern group 43, the driving gap 44 is located between the end of the driving electrode line 41 and the end of the driving dummy line 42 in the first direction D1. The driving gap 44 separates the driving electrode line 41 and the driving dummy line 42 from each other. Thereby, the driving dummy portion 31DD is separated from the driving electrode 31DP. In other words, the driving dummy line 42 is electrically insulated from the driving electrode 31DP.
驅動電極線41及驅動虛擬線42的形成材料,為上述金屬中的例如銅。在與感測面33S對向的平面視圖中,驅動電極線41及驅動虛擬線42各自具有相同的色相,例如黑色。 The material for forming the driving electrode lines 41 and the driving dummy lines 42 is, for example, copper among the above metals. In a plan view opposite to the sensing surface 33S, the driving electrode lines 41 and the driving dummy lines 42 each have the same hue, for example, black.
驅動電極線41及驅動虛擬線42係藉由在用以形成驅動電極線41及驅動虛擬線42的金屬薄膜進行黑化處理而具有黑色。或者,驅動電極線41及驅動虛擬線42係藉由在驅動電極線41及驅動虛擬線42進行黑化處理而具有黑色。黑化處理為例如氧化處理、或者對具有黑色的金屬膜進行鍍敷的鍍敷處理等。 The driving electrode lines 41 and the driving dummy lines 42 are black by performing a blackening process on a metal thin film for forming the driving electrode lines 41 and the driving dummy lines 42. Alternatively, the driving electrode lines 41 and the driving dummy lines 42 are blackened by performing a blackening process on the driving electrode lines 41 and the driving dummy lines 42. The blackening treatment is, for example, an oxidation treatment or a plating treatment for plating a black metal film.
參照圖5及圖6,說明構成驅動電極線41及驅動虛擬線42的基準圖案要素31RP。圖5為將圖4之驅動電極線41的一部分加以放大顯示的部分放大圖,圖5中,為了方便說明構成基準圖案要素31RP之電極線的配置,而將電極線的線寬誇大顯示。 The reference pattern elements 31RP constituting the driving electrode lines 41 and the driving dummy lines 42 will be described with reference to FIGS. 5 and 6. FIG. 5 is an enlarged view of a part of the driving electrode line 41 of FIG. 4. In FIG. 5, the line width of the electrode line is exaggerated for convenience in describing the arrangement of the electrode lines constituting the reference pattern element 31RP.
如圖5所示,基準圖案要素31RP具有1條主線Lm及1條副線Ls。主線Lm具有沿著與驅動電極31DP中之屬基準方向的第2方向D2形成屬既定角度的主線角度θ之延伸方向延伸的直線形狀,主線Lm係從第1主端點Pm1延伸至第2主端點Pm2。主線角度θ為包含於例如比0°大且比180°小之角度的範圍之既定角度,較佳為包含於45°以上135°以下的角度的範圍之既定角度,更佳為63.435°。 As shown in FIG. 5, the reference pattern element 31RP has one main line Lm and one sub line Ls. The main line Lm has a straight line shape extending along the extending direction of the main line angle θ forming a predetermined angle with the second direction D2 of the driving electrode 31DP, which is a reference direction. The main line Lm extends from the first main end point Pm1 to the second main line. End point Pm2. The main line angle θ is a predetermined angle included in a range of angles larger than 0 ° and smaller than 180 °, and is preferably a predetermined angle included in a range of angles of 45 ° to 135 °, and more preferably 63.435 °.
副線Ls係沿著與主線Lm正交的方向,具有從第2主端點Pm2延伸至副端點Ps的直線形狀,副線Ls的長度係主線Lm之一半的長度。當副線Ls的長度為單位長度LRP時,主線Lm的長度為2LRP。副線Ls的長度之單位長度LRP係與單位格子的一邊的長度相同的長度。副端點Ps相對於具有該副端點Ps的副線Ls,相當於位於主線Lm的延伸方向之其他基準圖案要素31RP的第1主端點Pm1。 The auxiliary line Ls has a linear shape extending from the second main end point Pm2 to the auxiliary end point Ps along a direction orthogonal to the main line Lm. The length of the auxiliary line Ls is a half of the length of the main line Lm. When the length of the auxiliary line Ls is the unit length LRP, the length of the main line Lm is 2 LRP. The unit length LRP of the length of the auxiliary line Ls is the same length as the length of one side of the unit grid. The secondary endpoint Ps is equivalent to the first primary endpoint Pm1 of the other reference pattern element 31RP located in the extending direction of the primary line Lm with respect to the secondary line Ls having the secondary endpoint Ps.
各基準圖案要素31RP進一步具有2條輔助線La。輔助線La的每一者係具有沿著與主線Lm所延伸的方向之延伸方向正交的方向延伸之直線形狀,且具有與副線Ls相同的長度。也就是說,輔助線La的長度為單位長度LRP。2條輔助線La中,一條輔助線La係從第2主端點Pm2延伸至第2補助端點Pa2,另一條輔助線La係從副端點Ps延伸至第1補助端點Pa1。主線Lm、副線Ls及輔助線La之各自的線寬為例如0.1μm以上12μm以下。 Each reference pattern element 31RP further includes two auxiliary lines La. Each of the auxiliary lines La has a linear shape extending in a direction orthogonal to the extending direction of the direction in which the main line Lm extends, and has the same length as the auxiliary line Ls. That is, the length of the auxiliary line La is a unit length LRP. Among the two auxiliary lines La, one auxiliary line La extends from the second main end point Pm2 to the second auxiliary end point Pa2, and the other auxiliary line La extends from the secondary end point Ps to the first auxiliary end point Pa1. The respective line widths of the main line Lm, the auxiliary line Ls, and the auxiliary line La are, for example, 0.1 μm to 12 μm.
各基準圖案要素31RP係仿效一邊具有單位長度LRP之格子圖案的一部分之形狀。亦即,各基準圖案要素31RP係仿效二維的格子圖案之形狀,該二維的格子圖案為主線Lm構成沿著延伸方向延伸的邊且副線Ls及輔助線La構成沿著與主線Lm正交的方向延伸的邊。二維的格子圖案具有屬單位格子的正方形呈二維連續的形狀。 Each reference pattern element 31RP follows the shape of a part of a lattice pattern having unit length LRP on one side. That is, each of the reference pattern elements 31RP imitates the shape of a two-dimensional lattice pattern, the two-dimensional lattice pattern constituting a side extending along the extending direction of the main line Lm, and the sub-line Ls and the auxiliary line La constituting along the main line Edges that extend in orthogonal directions. The two-dimensional lattice pattern has a two-dimensionally continuous shape with squares belonging to a unit lattice.
在與感測面33S對向的平面視圖中,當驅動面31S的複數個基準圖案要素31RP和感測面33S的複數個基準圖案要素重疊時,第1主端點Pm1、第2主端點Pm2、副端點Ps、第1補助端點Pa1及第2補助端點Pa2係位在正方格子的格子點。因此,驅動電極31DP的基準圖案要素31RP和感測電極33SP的基準圖案要素,一方面具有相互交叉的點(即重疊的點),另一方面不具有構成格子圖案的相同邊之線段。 In a plan view facing the sensing surface 33S, when the plurality of reference pattern elements 31RP of the driving surface 31S and the plurality of reference pattern elements of the sensing surface 33S overlap, the first main endpoint Pm1 and the second main endpoint Pm2, the sub-end point Ps, the first auxiliary end point Pa1, and the second auxiliary end point Pa2 are located at the grid points of a square grid. Therefore, the reference pattern element 31RP of the driving electrode 31DP and the reference pattern element of the sensing electrode 33SP have, on the one hand, points that cross each other (that is, overlapping points), and on the other hand, they do not have line segments of the same side that constitute a lattice pattern.
因此,在與感測面33S對向的平面視圖中,在驅動部分21D,在構成形成格子圖案的複數個單位格子的每一者的4條線段中,2條線段為驅動電極線41的一部分,2條線段為感測虛擬線52的一部分。相對地,在與感測面33S對向的平面視圖中,在感測部分21S,在構成形成格子圖案的複數個單位格子的每一者的4條線段中,2條線段為感測電極線51的一部分,2條線段為驅動虛擬線42的一部分。 Therefore, in the plan view opposite to the sensing surface 33S, in the driving portion 21D, of the 4 line segments constituting each of the plurality of unit cells forming a lattice pattern, 2 line segments are part of the driving electrode line 41 The 2 line segments are part of the sensing virtual line 52. In contrast, in a plan view opposite to the sensing surface 33S, in the sensing portion 21S, of the 4 line segments constituting each of the plurality of unit cells forming a lattice pattern, 2 line segments are sensing electrode lines A part of 51 and two line segments are a part of the driving virtual line 42.
結果,在與感測面33S對向的平面視圖中,驅動電極31DP和感測電極33SP不易被辨識為各別的構造體。 As a result, in a plan view facing the sensing surface 33S, the driving electrode 31DP and the sensing electrode 33SP are not easily recognized as separate structures.
圖6係將驅動電極31DP所具備的一個的驅動電容電極部31DPa加以放大顯示的部分放大圖,圖6中,為了方便說明驅動電極線41的電極線的配置,而將電極線的線寬誇大顯示。 FIG. 6 is an enlarged view of a partially enlarged driving capacitor electrode portion 31DPa included in the driving electrode 31DP. In FIG. 6, the line width of the electrode line is exaggerated in order to facilitate the description of the electrode line arrangement of the driving electrode line 41. display.
如圖6所示,驅動電容電極部31DPa所具備的各驅動電極線41係由沿第1方向D1排列的複數個基準圖案要素31RP所構成,且複數條驅動電極線41沿第2方向D2排列。 As shown in FIG. 6, each drive electrode line 41 included in the drive capacitor electrode portion 31DPa is composed of a plurality of reference pattern elements 31RP arranged along the first direction D1, and the plurality of drive electrode lines 41 are arranged along the second direction D2. .
在驅動電容電極部31DPa中,與構成驅動連接部31DPb的驅動電極線41連接的驅動電極線41係連接於驅動電極31DP所具備的墊31P。另一方面,與構成驅動連接部31DPb的驅動電極線41分離而設置的驅動電極線41在僅包含由複數個基準圖案要素31RP所構成的部分時,無法與驅動電極31DP所具備的墊31P電性連接。 In the driving capacitor electrode portion 31DPa, the driving electrode line 41 connected to the driving electrode line 41 constituting the driving connection portion 31DPb is connected to a pad 31P provided in the driving electrode 31DP. On the other hand, the drive electrode line 41 provided separately from the drive electrode line 41 constituting the drive connection portion 31DPb cannot be electrically connected to the pad 31P provided in the drive electrode 31DP when the drive electrode line 41 includes only a portion composed of a plurality of reference pattern elements 31RP. Sexual connection.
因此,驅動電容電極部31Dpa係包含具有與副線Ls相同長度的驅動連接線Lcd作為驅動電極線41的一部分,驅動連接線Lcd係將在第2方向D2相互相鄰的2條驅動電極線41相互電性連接。 Therefore, the driving capacitor electrode portion 31Dpa includes a driving connection line Lcd having the same length as the auxiliary line Ls as a part of the driving electrode line 41, and the driving connection line Lcd is two driving electrode lines 41 which are adjacent to each other in the second direction D2 Electrically connected to each other.
驅動連接線Lcd係從一條驅動電極線41所具有的一個基準圖案要素31RP的第2補助端點Pa2,延伸到在第2方向D2相互相鄰的驅動電極線41中一個基準圖案要素31RP所具有的主線Lm的延伸方向的中點為止。 The drive connecting line Lcd extends from the second auxiliary end point Pa2 of one reference pattern element 31RP in one drive electrode line 41 to one reference pattern element 31RP in the drive electrode lines 41 adjacent to each other in the second direction D2. Up to the midpoint of the extending direction of the main line Lm.
在一個驅動電容電極部31DPa中,沿第2方向D2排列的8條驅動連接線Lcd構成一個驅動連接線群,驅動連接線群係沿第1方向D1按每個驅動電容電極部31DPa設置。 In one driving capacitor electrode portion 31DPa, eight driving connecting lines Lcd arranged along the second direction D2 constitute one driving connecting line group, and the driving connecting line group is arranged for each driving capacitor electrode portion 31DPa in the first direction D1.
構成驅動電極31DP的驅動電極線41及驅動虛擬線42,亦可藉由形成驅動面31S的一個薄膜經由遮罩被蝕刻的方式形成,亦可藉由使用遮罩的物理蒸鍍法例如真空蒸鍍法或濺鍍法的方式形成。 The driving electrode line 41 and the driving dummy line 42 constituting the driving electrode 31DP can also be formed by etching a thin film forming the driving surface 31S through a mask, or by a physical evaporation method using a mask such as vacuum evaporation. It is formed by a plating method or a sputtering method.
參照圖7,說明觸控感測器用電極的構成。圖7中,為了方便說明驅動電極31DP的複數條驅動電極線的配置和感測電極33SP的複數條感測電極線的配置,而將驅動電極線的線寬和感測電極線的線寬誇大顯示。 The structure of the electrode for a touch sensor is demonstrated with reference to FIG. In FIG. 7, for the convenience of explaining the arrangement of the plurality of driving electrode lines of the driving electrode 31DP and the arrangement of the plurality of sensing electrode lines of the sensing electrode 33SP, the line width of the driving electrode line and the line width of the sensing electrode line are exaggerated. display.
如圖7所示,一個感測電極33SP具備有沿第2方向D2排列的複數個感測電容電極部33SPa、和連接相互相鄰的兩個感測電容電極部33SPa之間的感測連接部33SPb。複數個感測電極33SP係沿第1方向D1排列。 As shown in FIG. 7, one sensing electrode 33SP is provided with a plurality of sensing capacitor electrode portions 33SPa arranged along the second direction D2 and a sensing connection portion connecting two sensing capacitor electrode portions 33SPa adjacent to each other. 33SPb. The plurality of sensing electrodes 33SP are arranged along the first direction D1.
在感測電極33SP中,感測電容電極部33SPa的每一者和感測連接部33SPb的每一者係藉由複數條感測電極線51所構成。各感測電極33SP為複數條感測電極線51的集合。各感測電極線51包含例如具有圖案形狀的複數個基準圖案要素33RP,該圖案形狀係以在感測電極33SP中被制定為基準方向的第1方向D1為基準而 定。感測電極33SP的基準圖案要素33RP與驅動電極31DP的基準圖案要素31RP相比較之下,基準方向雖不同,但基準方向以外的構成是共同的。 In the sensing electrode 33SP, each of the sensing capacitor electrode portion 33SPa and each of the sensing connection portion 33SPb is constituted by a plurality of sensing electrode lines 51. Each sensing electrode 33SP is a collection of a plurality of sensing electrode lines 51. Each of the sensing electrode lines 51 includes, for example, a plurality of reference pattern elements 33RP having a pattern shape. The pattern shape is based on the first direction D1 defined as the reference direction in the sensing electrode 33SP. set. Although the reference pattern element 33RP of the sensing electrode 33SP is compared with the reference pattern element 31RP of the drive electrode 31DP, the reference direction is different, but the configurations other than the reference direction are common.
感測電容電極部33SPa具有例如沿第1方向D1隔著相等間隔排列的9條感測電極線51,各感測電極線51係沿第2方向D2延伸。感測連接部33SPb具有例如沿第1方向D1隔著等間隔排列的3條感測電極線51,各感測電極線51係沿第2方向D2延伸。 The sensing capacitor electrode portion 33SPa includes, for example, nine sensing electrode lines 51 arranged at equal intervals in the first direction D1, and each of the sensing electrode lines 51 extends in the second direction D2. The sensing connection portion 33SPb includes, for example, three sensing electrode lines 51 arranged at regular intervals in the first direction D1, and each of the sensing electrode lines 51 extends in the second direction D2.
構成感測電容電極部33SPa的9條感測電極線51中,位於第1方向D1的中央的3條感測電極線51係分別與構成感測連接部33SPb的3條感測電極線51連接。因此,在一個感測電極33SP中,沿第2方向D2連續地延伸的3條感測電極線51係位在第1方向D1的中央。 Of the nine sensing electrode lines 51 constituting the sensing capacitor electrode portion 33SPa, the three sensing electrode lines 51 located at the center of the first direction D1 are connected to the three sensing electrode lines 51 constituting the sensing connection portion 33SPb, respectively. . Therefore, in one sensing electrode 33SP, three sensing electrode lines 51 extending continuously in the second direction D2 are located at the center of the first direction D1.
另一方面,構成感測電容電極部33SPa的感測電極線51中,與位於第1方向D1的中央的3條感測電極線51不同的6條感測電極線51具有以下的構成。 On the other hand, among the sensing electrode lines 51 constituting the sensing capacitor electrode portion 33SPa, six sensing electrode lines 51 different from the three sensing electrode lines 51 located in the center of the first direction D1 have the following configuration.
在6條感測電極線51中,愈遠離感測電容電極部33SPa之第1方向D1的中央者,其沿第2方向D2的長度就愈小。且,6條感測電極線51的每一者,其沿第2方向D2的長度是以在第2方向D2的兩端相同長度的程度小於位在中央之感測電極線51。因此,在感測電容電極部33SPa中,由各感測電極線51的端部所構成之感測電容電極部33SPa的外形形狀為六角形形狀。 Of the six sensing electrode lines 51, the further away from the center of the first direction D1 of the sensing capacitor electrode portion 33SPa, the smaller the length along the second direction D2. In addition, the length of each of the six sensing electrode lines 51 in the second direction D2 is smaller than that of the sensing electrode lines 51 in the center by the same length at both ends of the second direction D2. Therefore, in the sensing capacitor electrode portion 33SPa, the outer shape of the sensing capacitor electrode portion 33SPa formed by the end portion of each sensing electrode line 51 is a hexagonal shape.
相對地,在構成感測連接部33SPb的3條感測電極線51中,沿第2方向D2的長度與沿3條感測電極線51之第1方向D1的合計寬度係大致相等。因此,在感測連接部33SPb中,由各感測電極線51的端部所構成之感測連接部33SPb的外形形狀為矩形形狀。 In contrast, among the three sensing electrode lines 51 constituting the sensing connection portion 33SPb, the length in the second direction D2 and the total width in the first direction D1 of the three sensing electrode lines 51 are substantially equal. Therefore, in the sensing connection portion 33SPb, the outer shape of the sensing connection portion 33SPb formed by the end portion of each sensing electrode line 51 is a rectangular shape.
在感測電容電極部33SPa中,與構成感測連接部33SPb的感測電極線51連接的感測電極線51係連接於感測電極33SP所具備的墊33P。另一方面,與構成感測連接部33SPb的感測電極線51分離而設置的感測電極線51在僅包含由複數個基準圖案要素33RP所構成的部分時,無法與感測電極33SP所具備的墊33P電性連接。 In the sensing capacitor electrode portion 33SPa, the sensing electrode line 51 connected to the sensing electrode line 51 constituting the sensing connection portion 33SPb is connected to a pad 33P included in the sensing electrode 33SP. On the other hand, when the sensing electrode line 51 provided separately from the sensing electrode line 51 constituting the sensing connection portion 33SPb includes only a portion composed of a plurality of reference pattern elements 33RP, it cannot be provided with the sensing electrode 33SP. The pad 33P is electrically connected.

Is less than the sensed virtual line 52 in the center.
因此,在感測虛擬部33SD中,由各感測虛擬線52的端部所構成之感測虛擬部33SD的外形形狀為六角形形狀。 Therefore, in the sensing dummy portion 33SD, the outer shape of the sensing dummy portion 33SD formed by the end of each sensing dummy line 52 is a hexagonal shape.
包含於一個感測虛擬部33SD的感測虛擬線52中,位於第1方向D1的中央之感測虛擬線52的一方 具有複數個虛擬內間隙52a,複數個虛擬內間隙52a係沿第2方向D2隔著等間隔排列。複數個虛擬內間隙52a係沿第1方向D1及第2方向D2位在各感測虛擬部33SD。感測面33S之虛擬內間隙52a的每一者,在與感測面33S對向的平面視圖中,係與相互不同的驅動連接線Lcd重疊。 One of the sensing virtual lines 52 included in one sensing virtual part 33SD, which is located at the center of the first direction D1.

在第2方向D2上,感測虛擬部33SD和感測電容電極部33SPa的一部分係交互連續地排列。在觸控感測器用電極21的一部分中,於第2方向D2上,構成感測虛擬部33SD的感測虛擬線52和構成感測電容電極部33SPa的感測電極線51係交互連續地排列。在第2方向D2上交互連續的感測電極線51和感測虛擬線52係構成一個感測圖案群53,在第2方向D2相互相鄰的感測電極線51和感測虛擬線52係分別包含共用的一個基準圖案要素33RP的一部分。 In the second direction D2, a part of the sensing dummy portion 33SD and the sensing capacitor electrode portion 33SPa are alternately and continuously arranged. In a part of the touch sensor electrode 21, in the second direction D2, the sensing virtual line 52 constituting the sensing virtual portion 33SD and the sensing electrode line 51 constituting the sensing capacitor electrode portion 33SPa are alternately and continuously arranged. . The sensing electrode lines 51 and the sensing virtual lines 52 that are alternately continuous in the second direction D2 form a sensing pattern group 53. The sensing electrode lines 51 and the sensing virtual lines 52 that are adjacent to each other in the second direction D2 are Each of them includes a part of a common reference pattern element 33RP.
在感測圖案群53中,感測間隙54係位在第2方向D2之感測電極線51的端部和感測虛擬線52的端部之間。感測間隙54係使感測電極線51和感測虛擬線52相互分離。藉此,感測虛擬部33SD會自感測電極33SP分離。換言之,感測虛擬部33SD會與感測電極33SP電性絕緣。 In the sensing pattern group 53, the sensing gap 54 is located between the end of the sensing electrode line 51 and the end of the sensing virtual line 52 in the second direction D2. The sensing gap 54 separates the sensing electrode line 51 and the sensing dummy line 52 from each other. Thereby, the sensing dummy portion 33SD is separated from the sensing electrode 33SP. In other words, the sensing dummy portion 33SD is electrically insulated from the sensing electrode 33SP.

In the plane opposite to the sensing surface 33S In the plan view, the sensing electrode lines 51 and the sensing virtual lines 52 each have the same hue, for example, black.
感測電極線51及感測虛擬線52係藉由在用以形成感測電極線51及感測虛擬線52的金屬薄膜進行黒化處理而具有黒色。或者,感測電極線51及感測虛擬線52係藉由在感測電極線51及感測虛擬線52進行黒化處理而具有黒色。黒化處理為例如氧化處理、或者對具有黒色的金屬膜進行鍍敷的鍍敷處理等。 The sensing electrode line 51 and the sensing dummy line 52 have a black color by subjecting the metal thin film used to form the sensing electrode line 51 and the sensing dummy line 52 to a hazing process. Alternatively, the sensing electrode lines 51 and the sensing virtual lines 52 have a black color by performing an ablative process on the sensing electrode lines 51 and the sensing virtual lines 52. The halogenation treatment is, for example, an oxidation treatment or a plating treatment for plating a metal film having a ochre color.
對感測電極線51及感測虛擬線52的黒化處理、和對驅動電極線41及驅動虛擬線42的黒化處理,一般是在相互不同的時間點進行。因此,感測電極線51及感測虛擬線52所具有之黑色中的明度及彩度的至少一者,係以與驅動電極線41及驅動虛擬線42所具有之黑色中的明度及彩度的至少一者彼此不同的情況居多。 The process of converting the sensing electrode line 51 and the sensing dummy line 52 and the process of driving the electrode line 41 and the driving dummy line 42 are generally performed at different time points. Therefore, at least one of the lightness and chroma in the black of the sensing electrode line 51 and the sensing virtual line 52 is the same as the lightness and chroma in the black of the driving electrode line 41 and the driving virtual line 42. Most of them are different from each other.
又,辨識觸控感測器用電極21時,驅動電極線41及驅動虛擬線42係透過透明介電體基板33被辨識。因此,驅動電極31DP所具有的顏色和感測電極33SP所具有的顏色,亦以被辨識為彼此不同的顏色居多。 When the touch sensor electrodes 21 are identified, the driving electrode lines 41 and the driving dummy lines 42 are identified through the transparent dielectric substrate 33. Therefore, the colors of the driving electrode 31DP and the sensing electrode 33SP are mostly colors recognized as different from each other.
在觸控感測器用電極21中,在與感測面33S對向的平面視圖中,驅動電容電極部31DPa係與位於相互相鄰的2條感測電極33SP之間的感測虛擬部33SD呈立體重疊。換言之,在與感測面33S對向的平面視圖中,以驅動電容電極部31DPa與感測虛擬部33SD重疊的方式,使驅動電容電極部31DPa及感測虛擬部33SD呈立體配置。 In the touch sensor electrode 21, in a plan view opposite to the sensing surface 33S, the driving capacitor electrode portion 31DPa is a sensing virtual portion 33SD located between two sensing electrodes 33SP adjacent to each other. Three-dimensional overlap. In other words, in a plan view opposite to the sensing surface 33S, the driving capacitor electrode portion 31DPa and the sensing dummy portion 33SD are arranged in a three-dimensional manner so that the driving capacitor electrode portion 31DPa and the sensing dummy portion 33SD overlap.
因此,在與感測面33S對向的平面視圖中,構成驅動電容電極部31DPa的驅動電極線41係與構成感測虛擬部33SD的感測虛擬線52協同動作,而形成由基準圖案要素31RP、33RP所構成的正方格子。亦即,構成驅動電容電極部31DPa的驅動電極線41和構成感測虛擬部33SD的感測虛擬線52,係在共同的一個格子圖案的驅動部分21D中,構成相互交叉之各別的線段。 Therefore, in a plan view facing the sensing surface 33S, the driving electrode line 41 constituting the driving capacitor electrode portion 31DPa and the sensing virtual line 52 constituting the sensing virtual portion 33SD cooperate to form a reference pattern element 31RP. , 33RP composed of a square grid. That is, the driving electrode lines 41 constituting the driving capacitor electrode portion 31DPa and the sensing dummy lines 52 constituting the sensing dummy portion 33SD are connected to each other in a common grid-shaped driving portion 21D and constitute separate line segments crossing each other.
另一方面,在觸控感測器用電極21中,在與感測面33S對向的平面視圖中,感測電容電極部33SPa係與位於相互相鄰的2條驅動電極31DP之間的驅動虛擬部31DD呈立體重疊。換言之,在與感測面33S對向的平面視圖中,以感測電容電極部33SPa與驅動虛擬部31DD重疊的方式,使感測電容電極部33SPa及驅動虛擬部31DD呈立體配置。 On the other hand, in the touch sensor electrode 21, in a plan view facing the sensing surface 33S, the sensing capacitor electrode portion 33SPa is a driving dummy between two driving electrodes 31DP located adjacent to each other. The sections 31DD are three-dimensionally overlapped. In other words, in a plan view opposite to the sensing surface 33S, the sensing capacitor electrode portion 33SPa and the driving dummy portion 31DD are arranged in a three-dimensional manner so that the sensing capacitor electrode portion 33SPa overlaps with the driving dummy portion 31DD.
因此,在與感測面33S對向的平面視圖中,構成感測電容電極部33SPa的感測電極線51係與構成驅動虛擬部31DD的驅動虛擬線42協同動作,而形成由基準圖案要素31RP、33RP所構成的正方格子。亦即,構成感測電容電極部33SPa的感測電極線51和構成驅動虛擬部31DD的驅動虛擬線42,係在先前的格子圖案的感測部分21S,構成相互交叉之各別的線段。 Therefore, in a plan view facing the sensing surface 33S, the sensing electrode line 51 constituting the sensing capacitor electrode portion 33SPa and the driving virtual line 42 constituting the driving virtual portion 31DD cooperate to form a reference pattern element 31RP. , 33RP composed of a square grid. That is, the sensing electrode line 51 constituting the sensing capacitor electrode portion 33SPa and the driving dummy line 42 constituting the driving dummy portion 31DD are connected to the sensing portion 21S of the previous grid pattern and constitute separate line segments crossing each other.
又,在與感測面33S對向的平面視圖中,驅動連接部31DPb係與感測連接部33SPb呈立體重疊。換言之,在與感測面33S對向的平面視圖中,以驅動連接部31DPb與感測連接部33SPb重疊的方式,使驅動連接 部31DPb及感測連接部33SPb呈立體配置。因此,在與感測面33S對向的平面視圖中,構成驅動連接部31DPb的驅動電極線41係與構成感測連接部33SPb的感測電極線51協同動作,而形成由基準圖案要素31RP、33RP所構成的正方格子。亦即,構成驅動連接部31DPb的驅動電極線41和構成感測連接部33SPb的感測電極線51,係在先前的格子圖案的與驅動部分21D及感測部分21S相異的部分,構成相互交叉之各別的線段。 In addition, in a plan view facing the sensing surface 33S, the driving connection portion 31DPb is three-dimensionally overlapped with the sensing connection portion 33SPb. In other words, in a plan view facing the sensing surface 33S, the driving connection portion 31DPb and the sensing connection portion 33SPb overlap so that the driving connection The portion 31DPb and the sensing connection portion 33SPb are arranged in a three-dimensional manner. Therefore, in a plan view facing the sensing surface 33S, the driving electrode line 41 constituting the driving connection portion 31DPb and the sensing electrode line 51 constituting the sensing connection portion 33SPb cooperate to form a reference pattern element 31RP, A square grid composed of 33RP. That is, the driving electrode line 41 constituting the driving connection portion 31DPb and the sensing electrode line 51 constituting the sensing connection portion 33SPb are formed in portions of the previous grid pattern that are different from the driving portion 21D and the sensing portion 21S, and constitute each other. Intersecting individual line segments.
參照圖8及圖9,說明觸控感測器用電極的作用。在圖8及圖9中,為了方便說明,省略了設有驅動電極31DP之透明基板31的圖示。又,圖8中,為了方便說明,驅動虛擬線42及感測虛擬線52係以虛線表示。 The function of the electrode for a touch sensor will be described with reference to FIGS. 8 and 9. In FIGS. 8 and 9, the illustration of the transparent substrate 31 provided with the driving electrode 31DP is omitted for convenience of explanation. In addition, in FIG. 8, for convenience of explanation, the driving virtual line 42 and the sensing virtual line 52 are indicated by dotted lines.
如圖8所示,選擇電路34將驅動訊號輸出到驅動電極31DP。例如,在與感測面33S對向的平面視圖中,在第2方向D2上於相互相鄰的驅動電容電極部31DPa與感測電容電極部33SPa之間形成電場EF。在驅動電容電極部31DPa和感測電容電極部33SPa中,於構成驅動電容電極部31DPa的一條驅動電極線41和構成感測電容電極部33SPa的一條感測電極線51之間形成電場EF。 As shown in FIG. 8, the selection circuit 34 outputs a driving signal to the driving electrode 31DP. For example, in a plan view facing the sensing surface 33S, an electric field EF is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa adjacent to each other in the second direction D2. In the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa, an electric field EF is formed between one driving electrode line 41 constituting the driving capacitor electrode portion 31DPa and one sensing electrode line 51 constituting the sensing capacitor electrode portion 33SPa.
驅動電容電極部31DPa和感測電容電極部33SPa由於在與感測面33S對向的平面視圖中沒有相互重疊,所以是容易受到來自透明介電體基板33的外側 之電氣的影響的部分。因此,驅動電容電極部31Dpa與感測電容電極部33SPa之間的電場EF也形成於容易受到來自透明介電體基板33的外側之電氣的影響的部分。 The driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa do not overlap each other in a plan view facing the sensing surface 33S, and therefore are easily exposed from the outside of the transparent dielectric substrate 33 Of its electrical impact. Therefore, the electric field EF between the driving capacitor electrode portion 31Dpa and the sensing capacitor electrode portion 33SPa is also formed in a portion that is susceptible to electrical influence from the outside of the transparent dielectric substrate 33.
當人的手指F接近這樣的觸控感測器用電極21時,由於接觸到手指F的電場EF會透過人體放電,所以形成於驅動電極31DP和感測電極33SP之間的靜電電容的大小會改變。如上所述,由於電場EF在從驅動電容電極部31DPa的電極線朝向感測電容電極部33SPa的電極線延伸時,係位在容易受到來自外側的電氣的影響的部分,所以電場EF容易受到人的手指F影響。因此,在觸控感測器用電極21中,於驅動電容電極部31DPa和感測電容電極部33SPa之間,對於人的手指F的接觸之感度會變高。結果,檢測人的手指F所接觸的位置之感度會變高。 When a human finger F approaches such a touch sensor electrode 21, the electric field EF in contact with the finger F will be discharged through the human body, so the size of the electrostatic capacitance formed between the driving electrode 31DP and the sensing electrode 33SP will change. . As described above, when the electric field EF extends from the electrode line of the driving capacitor electrode portion 31DPa toward the electrode line of the sensing capacitor electrode portion 33SPa, the electric field EF is located in a portion that is susceptible to electrical influence from the outside. The influence of the finger F. Therefore, in the touch sensor electrode 21, the sensitivity to the contact of the human finger F between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa becomes high. As a result, the sensitivity of detecting the position touched by the human finger F becomes high.
另一方面,如圖9所示,在與感測面33S對向的平面視圖中,在形成驅動連接部31DPb的驅動電極線41和形成感測連接部33SPb的感測電極線51呈立體的交叉的部分,形成靜電電容。因此,當選擇電路34將驅動訊號輸出到驅動電極31DP時,具有大致直線形狀的電場EF係從驅動連接部31DPb的一條驅動電極線41朝向感測連接部33SPb的一條感測電極線51延伸。因此,電場EF位在難以受到來自透明介電體基板33的外側之電氣的影響的部分。 On the other hand, as shown in FIG. 9, in a plan view facing the sensing surface 33S, the driving electrode line 41 forming the driving connection portion 31DPb and the sensing electrode line 51 forming the sensing connection portion 33SPb are three-dimensional. The intersecting portions form electrostatic capacitance. Therefore, when the selection circuit 34 outputs a driving signal to the driving electrode 31DP, the electric field EF having a substantially linear shape extends from one driving electrode line 41 of the driving connection portion 31DPb toward one sensing electrode line 51 of the sensing connection portion 33SPb. Therefore, the electric field EF is located at a portion that is hardly affected by the electric influence from the outside of the transparent dielectric substrate 33.
因此,即便人的手指F接近觸控感測器用電極21中驅動連接部31DPb和感測連接部33SPb呈立體 重疊的部分,手指F接近前之電場EF的狀態和手指F接近後之電場EF的狀態也不會大幅改變。結果,在觸控感測器用電極21中,於驅動連接部31DPb和感測連接部33SPb重疊的部分,觸控面板20對於輸入到觸控感測器用電極21之雜訊的耐受性變高。 Therefore, even if the human finger F approaches the touch sensor electrode 21, the driving connection portion 31DPb and the sensing connection portion 33SPb are three-dimensional. In the overlapped portion, the state of the electric field EF before the finger F and the state of the electric field EF after the finger F are not significantly changed. As a result, among the touch sensor electrodes 21, in a portion where the driving connection portion 31DPb and the sensing connection portion 33SPb overlap, the touch panel 20 has higher resistance to noise input to the touch sensor electrodes 21. .
在觸控感測器用電極21中,在與感測面33S對向的平面視圖中,驅動電極線41和感測虛擬線52的組合形成一個格子圖案,且感測電極線51和驅動虛擬線42的組合形成一個格子圖案。因此,驅動電極31DP所具有的黒色和感測電極33SP所具有的黒色難以個別地被辨識。因此,即便驅動電極31DP所具有的黒色和感測電極33SP所具有的黒色中之明度及彩度的至少一者不同,驅動電極31DP的黒色和感測電極33SP的黒色之差異也不易引人注目。結果,會抑制驅動電極31DP及感測電極33SP的交界被辨識,且會抑制驅動電極31DP和感測電極33SP被辨識。 In the touch sensor electrode 21, in a plan view facing the sensing surface 33S, the combination of the driving electrode line 41 and the sensing virtual line 52 forms a grid pattern, and the sensing electrode line 51 and the driving virtual line The combination of 42 forms a lattice pattern. Therefore, it is difficult to distinguish the black color of the driving electrode 31DP and the black color of the sensing electrode 33SP individually. Therefore, even if the lightness and chroma of the black color of the driving electrode 31DP and the black color of the sensing electrode 33SP are different, the difference between the black color of the driving electrode 31DP and the black color of the sensing electrode 33SP is not noticeable. . As a result, the boundary between the driving electrode 31DP and the sensing electrode 33SP is inhibited from being identified, and the driving electrode 31DP and the sensing electrode 33SP are inhibited from being identified.
如以上說明所示,根據第1實施形態,可得到以下列舉的優點。 As described above, according to the first embodiment, the advantages listed below can be obtained.
(1)在與感測面33S對向的平面視圖中,驅動電極線41和感測虛擬線52的組合形成一個格子圖案,且感測電極線51和驅動虛擬線42的組合形成一個格子圖案。因此,驅動電極31DP所具有的顏色和感測電極33SP所具有的顏色難以個別地被辨識。因此,即便驅動電極31DP所具有的顏色和感測電極33SP所具有的顏色相互不同,驅動電極31DP的顏色和感測電極33SP 的顏色之差異也不易引人注目。結果,會抑制驅動電極31DP及感測電極33SP的交界被辨識,且會抑制驅動電極31DP和感測電極33SP被辨識。 (1) In a plan view opposite to the sensing surface 33S, the combination of the driving electrode line 41 and the sensing virtual line 52 forms a grid pattern, and the combination of the sensing electrode line 51 and the driving virtual line 42 forms a grid pattern. . Therefore, it is difficult for the color of the driving electrode 31DP and the color of the sensing electrode 33SP to be individually identified. Therefore, even if the color of the driving electrode 31DP and the color of the sensing electrode 33SP are different from each other, the color of the driving electrode 31DP and the sensing electrode 33SP are different from each other. The difference in color is also not noticeable. As a result, the boundary between the driving electrode 31DP and the sensing electrode 33SP is inhibited from being identified, and the driving electrode 31DP and the sensing electrode 33SP are inhibited from being identified.
(2)在驅動電極31DP和感測電極33SP中,在與感測面33S對向的平面視圖中於不會相互重疊的驅動電容電極部31DPa和感測電容電極部33SPa之間形成靜電電容。驅動電容電極部31DPa和感測電容電極部33SPa之間的電容部分,由於是容易受到來自透明介電體基板33的外側之電氣的影響的部分,所以當導電體靠近觸控感測器用電極21時,驅動電容電極部31DPa和感測電容電極部33SPa之間的靜電電容容易改變。因此,檢測導電體相對於觸控感測器用電極21的位置之精確度會提高。 (2) In the driving electrode 31DP and the sensing electrode 33SP, an electrostatic capacitance is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa that do not overlap each other in a plan view facing the sensing surface 33S. The capacitance portion between the driving capacitance electrode portion 31DPa and the sensing capacitance electrode portion 33SPa is a portion that is susceptible to electrical influence from the outside of the transparent dielectric substrate 33. Therefore, when the conductive body approaches the touch sensor electrode 21 At this time, the electrostatic capacitance between the driving capacitance electrode portion 31DPa and the sensing capacitance electrode portion 33SPa is easily changed. Therefore, the accuracy of detecting the position of the conductive body with respect to the touch sensor electrode 21 is improved.
(3)在格子圖案的驅動部分21D中,單位格子係由驅動電極線41的一部分和感測虛擬線52的一部分所構成,且在感測部分21S中,單位格子係由感測電極線51的一部分和驅動虛擬線42的一部分所構成。因此,在與感測面33S對向的平面視圖中,可進一步抑制位於驅動面31S的驅動電極31DP和位於感測面33S的感測電極33SP被辨識為各別的構造體。 (3) In the driving portion 21D of the lattice pattern, the unit lattice system is composed of a part of the driving electrode line 41 and the sensing virtual line 52, and in the sensing portion 21S, the unit lattice system is composed of the sensing electrode line 51. And a part of the driving virtual line 42. Therefore, in a plan view facing the sensing surface 33S, the driving electrode 31DP on the driving surface 31S and the sensing electrode 33SP on the sensing surface 33S can be further suppressed from being recognized as separate structures.
(4)由於驅動電極線41和感測電極線51包含複數個基準圖案要素31RP、33RP,所以容易設計驅動電極31DP和感測電極33SP。 (4) Since the driving electrode line 41 and the sensing electrode line 51 include a plurality of reference pattern elements 31RP and 33RP, it is easy to design the driving electrode 31DP and the sensing electrode 33SP.
(5)主線角度θ由於比0°大且比180°小,所以可使構成格子圖案的複數個線段的每一者相對於第1方向D1及第2方向D2傾斜。 (5) Since the main line angle θ is larger than 0 ° and smaller than 180 °, each of the plurality of line segments constituting the lattice pattern can be inclined with respect to the first direction D1 and the second direction D2.
(6)即便在驅動電極線41和感測虛擬線52之間明度及彩度的至少一者相互不同,且在感測電極線51和驅動虛擬線42之間明度及彩度的至少一者相互不同,驅動電極31DP和感測電極33SP的顏色之差異也不易引人注目。 (6) Even if at least one of lightness and chroma is different between the driving electrode line 41 and the sensing virtual line 52, and at least one of lightness and chroma is between the sensing electrode line 51 and the driving virtual line 42. Different from each other, the difference in color of the driving electrode 31DP and the sensing electrode 33SP is not easily noticeable.

For example, each of the driving electrode line 41, the driving dummy line 42, the sensing electrode line 51, and the sensing dummy line 52 may have a structure having a metallic luster or a structure having a light transmittance. In this case, a material for forming the electrode line having light permeability may be a metal oxide film such as zinc oxide, and a composite oxide film such as indium tin oxide or indium gallium zinc oxide.

In addition, the electrode wire having a ocher color is not limited to a metal wire subjected to a halogenation treatment, and a conductive film such as a graphene film may be used.
即便是這樣的構成,由於透明介電體基板33係位在驅動電極31DP和感測電極33SP之間,所以驅動電極31DP具有的顏色和感測電極33SP具有的顏色,從透明介電體基板33的表面觀看差異甚大。因此,可獲得甚多基於上述(1)的優點。 Even with such a configuration, since the transparent dielectric substrate 33 is located between the driving electrode 31DP and the sensing electrode 33SP, the color of the driving electrode 31DP and the color of the sensing electrode 33SP are obtained from the transparent dielectric substrate 33. The surface viewing varies widely. Therefore, many advantages based on the above (1) can be obtained.

On the other hand, between the sensing electrode 33SP and the sensing dummy portion 33SD and the driving electrode 31DP, the three colors At least one of the characteristics is different. Even with such a configuration, the advantages based on the above (1) can be obtained.
‧驅動電極31DP、驅動虛擬部31DD、感測電極33SP及感測虛擬部33SD亦可各自具有相互相同顏色的屬性。即便是這樣的構成,在驅動電極31DP及驅動虛擬部31DD,和感測電極33SP及感測虛擬部33SD之間,也存在著透明介電體基板33。因此,在與感測面33S對向的平面視圖中,驅動電極31DP及驅動虛擬部31DD的顏色、和感測電極33SP與感測虛擬部33SD的顏色,可彼此差異甚大。因此,可獲得基於上述(1)的優點。 ‧ The driving electrode 31DP, the driving dummy portion 31DD, the sensing electrode 33SP, and the sensing dummy portion 33SD may each have attributes of the same color. Even with such a configuration, a transparent dielectric substrate 33 exists between the driving electrode 31DP and the driving dummy portion 31DD, and the sensing electrode 33SP and the sensing dummy portion 33SD. Therefore, in a plan view opposite to the sensing surface 33S, the colors of the driving electrodes 31DP and the driving dummy portion 31DD and the colors of the sensing electrode 33SP and the sensing dummy portion 33SD may be greatly different from each other. Therefore, the advantages based on the above (1) can be obtained.
‧主線角度θ亦可為0°。亦即,構成格子圖案的一個格子的四個邊,亦可為沿第1方向D1延伸成直線狀的2邊、和沿第2方向D2延伸成直線狀的2邊。即便是這樣的構成,只要是格子圖案能以複數個基準圖案要素31RP形成的構成,就可獲得基於上述(4)的優點。 ‧The main line angle θ can also be 0 °. That is, the four sides of one grid constituting the lattice pattern may be two sides extending linearly in the first direction D1 and two sides extending linearly in the second direction D2. Even in such a configuration, as long as the lattice pattern can be formed with a plurality of reference pattern elements 31RP, the advantage based on the above (4) can be obtained.

圖10及圖11中,為了方便說明構成驅動電極31DP的複數條驅動電極線、及構成感測電極33SP的複數條感測電極線的配置,而將驅動電極線的線寬及感測電極線的線寬誇大顯示。又,雖然驅動虛擬線42在驅動面31S的位置與驅動電極線41彼此相異,但是因為構成驅動虛擬線42的基準圖案要素31RP係與驅動電極線41共同,所以省略驅動虛擬線42的詳細說明。雖然感測虛擬線52在感測面33S的位置與感測電極線51彼此相異,但是因為構成感測虛擬線52的基準圖案要素33RP係與感測電極線51共同,所以省略感測虛擬線52的詳細說明。 In FIGS. 10 and 11, in order to facilitate the description of the arrangement of the plurality of driving electrode lines constituting the driving electrode 31DP and the plurality of sensing electrode lines constituting the sensing electrode 33SP, the line width and the sensing electrode lines of the driving electrode lines are changed. The line width is exaggerated. Although the position of the driving dummy line 42 on the driving surface 31S and the driving electrode line 41 are different from each other, since the reference pattern element 31RP constituting the driving dummy line 42 is common to the driving electrode line 41, details of the driving dummy line 42 are omitted. Instructions. Although the position of the sensing virtual line 52 on the sensing surface 33S and the sensing electrode line 51 are different from each other, since the reference pattern element 33RP constituting the sensing virtual line 52 is common to the sensing electrode line 51, the sensing virtual line is omitted. Detailed description of line 52.
如圖10所示,驅動電極31DP為複數條驅動電極線41的集合。複數條驅動電極線41係沿第2方向D2隔著等間隔排列,且複數條驅動電極線41的每一者沿第1方向D1延伸。各驅動電極線41係由複數個基準圖案要素31RP所構成,在驅動電極線41中,複數個基準圖案要素31RP係沿第1方向D1排列。 As shown in FIG. 10, the driving electrode 31DP is a collection of a plurality of driving electrode lines 41. The plurality of driving electrode lines 41 are arranged at equal intervals in the second direction D2, and each of the plurality of driving electrode lines 41 extends in the first direction D1. Each drive electrode line 41 is composed of a plurality of reference pattern elements 31RP. In the drive electrode line 41, the plurality of reference pattern elements 31RP are arranged in the first direction D1.
基準圖案要素31RP具備有1條主線Lm及1條副線Ls。主線Lm具有與驅動電極31DP中之屬基準方向的第2方向D2形成既定角度的主線角度θ之直線形狀,主線Lm係從第1主端點Pm1延伸到第2主端點Pm2。主線角度θ為包含於比0°大且比180°小之角度的範圍之既定角度,較佳為包含於45°以上135°以下的角度的範圍之既定角度,更佳為63.435°。主線角度θ亦可為0°。與第2方向D2形成主線角度θ的方向為延伸方向。 The reference pattern element 31RP includes one main line Lm and one sub line Ls. The main line Lm has a straight line shape with a main line angle θ forming a predetermined angle with the second direction D2 of the driving electrode 31DP, which is a reference direction. The main line Lm extends from the first main end point Pm1 to the second main end point Pm2. The main line angle θ is a predetermined angle included in a range of angles larger than 0 ° and smaller than 180 °, preferably a predetermined angle included in a range of angles of 45 ° to 135 °, and more preferably 63.435 °. The main line angle θ may also be 0 °. A direction forming a main line angle θ with the second direction D2 is an extending direction.
副線Ls具有沿著與主線Lm正交的方向,從第2主端點Pm2延伸到副端點Ps的直線形狀,副線Ls的長度為主線Lm的一半的長度。當副線Ls的長度為單位長度LRP時,主線Lm的長度為2LRP。副端點Ps相對於具有副端點Ps的副線Ls,為位於副線Ls的延伸方向之其他基準圖案要素31RP的第1主端點Pm1。 The auxiliary line Ls has a linear shape extending from the second main end point Pm2 to the auxiliary end point Ps in a direction orthogonal to the main line Lm. The length of the auxiliary line Ls is half the length of the main line Lm. When the length of the auxiliary line Ls is the unit length LRP, the length of the main line Lm is 2 LRP. The secondary endpoint Ps is the first primary endpoint Pm1 of the other reference pattern element 31RP located in the extending direction of the secondary line Ls with respect to the secondary line Ls having the secondary endpoint Ps.
各基準圖案要素31RP進一步具有2條輔助線La。輔助線La的每一者具有沿著主線Lm所延伸的方向之延伸方向延伸的直線形狀,且具有與副線Ls為相同長度的單位長度LRP。在2條輔助線La中,其中一條輔助線La係從第1主端點Pm1延伸到第1補助端點Pa1,另一條的輔助線La係從第2主端點Pm2延伸到第2補助端點Pa2。 Each reference pattern element 31RP further includes two auxiliary lines La.

That is, each reference pattern element 31RP imitates the shape of a two-dimensional lattice pattern. The two-dimensional lattice pattern constitutes a main line Lm and an auxiliary line La constituting sides extending along the extending direction, and the sub-line Ls constitutes along with and The main line Lm extends in a direction orthogonal to the side. The two-dimensional lattice pattern has a two-dimensionally continuous shape with squares belonging to a unit lattice.
當複數個驅動電極31DP和複數個感測電極33SP夾著透明介電體基板33而呈立體重疊時,第1主端點Pm1、第2主端點Pm2、副端點Ps、第1補助端點Pa1及第2補助端點Pa2係位在格子圖案的格子點。因此,驅動電極31DP的基準圖案要素31RP和感測電極 33SP的基準圖案要素33RP,一方面具有相互交叉的點,另一方面不具有構成正方格子的相同邊的線段。 When the plurality of driving electrodes 31DP and the plurality of sensing electrodes 33SP are three-dimensionally overlapped with the transparent dielectric substrate 33 interposed therebetween, the first main terminal Pm1, the second main terminal Pm2, the secondary terminal Ps, and the first auxiliary terminal The points Pa1 and the second auxiliary endpoint Pa2 are located at grid points of a grid pattern. Therefore, the reference pattern element 31RP of the driving electrode 31DP and the sensing electrode The 33SP reference pattern element 33RP has points that cross each other on the one hand, and does not have line segments of the same side that constitute a square lattice.
如圖11所示,感測電極33SP為複數條感測電極線51的集合,複數條感測電極線51係沿第1方向D1隔著等間隔排列,且複數條感測電極線51的每一者沿第2方向D2延伸。各感測電極線51係由以第1方向D1為基準方向的基準圖案要素33RP所構成,在感測電極線51中,複數個基準圖案要素33RP係沿第2方向D2排列。 As shown in FIG. 11, the sensing electrode 33SP is a collection of a plurality of sensing electrode lines 51.

One extends in the second direction D2. Each of the sensing electrode lines 51 is composed of a reference pattern element 33RP with the first direction D1 as a reference direction. In the sensing electrode line 51, a plurality of reference pattern elements 33RP are arranged along the second direction D2.

In addition, the sensing capacitor electrode portion 33SPa and the driving dummy portion 31DD are three-dimensionally overlapped, and a part of a lattice pattern is formed.
‧驅動面31S的基準圖案要素31RP中的輔助線La的構成和感測面33S的基準圖案要素33RP中的輔助線La的構成,亦可彼此相異。亦即,驅動面31S的基準圖案要素31RP和感測面33S的基準圖案要素 33RP的各個,只要具備上述的主線Lm和副線Ls即可。於此情況,驅動面31S中的基準圖案要素31RP所含之輔助線La的數量,亦可與感測面33S中的基準圖案要素33RP所含之輔助線La的數量不同。又,驅動面31S中輔助線La相對於基準圖案要素31RP之位置和感測面33S中輔助線La相對於基準圖案要素33RP之位置,亦可彼此相異。總之,驅動電極線和感測電極線只要在與感測面33S對向的平面視圖中,具有用以形成格子圖案的的互補關係即可。 The configuration of the auxiliary line La in the reference pattern element 31RP of the driving surface 31S and the configuration of the auxiliary line La in the reference pattern element 33RP of the sensing surface 33S may be different from each other. That is, the reference pattern element 31RP of the driving surface 31S and the reference pattern element of the sensing surface 33S Each of the 33RPs may be provided with the main line Lm and the sub-line Ls described above. In this case, the number of auxiliary lines La included in the reference pattern element 31RP in the driving surface 31S may be different from the number of auxiliary lines La included in the reference pattern element 33RP in the sensing surface 33S. The position of the auxiliary line La with respect to the reference pattern element 31RP on the driving surface 31S and the position of the auxiliary line La with respect to the reference pattern element 33RP on the sensing surface 33S may be different from each other. In short, the driving electrode line and the sensing electrode line only need to have a complementary relationship for forming a lattice pattern in a plan view opposite to the sensing surface 33S.
詳細闡述之,如圖12所示,基準圖案要素31RP和基準圖案要素33RP的各個係由一條主線Lm和一條副線Ls所構成。此時,在與感測面33S對向的平面視圖中,形成由在第2方向D2相互相鄰的2條驅動電極線41和在第1方向D1相互相鄰的2條感測電極線51所包圍的區域之電極線間隙V。電極線間隙V係由五個單位格子所構成的十字狀,位於電極線間隙V中央的一個單位格子係第1方向D1的兩側和第2方向D2的兩側被其他單位格子包夾而成的形狀。 To elaborate, as shown in FIG. 12, each of the reference pattern element 31RP and the reference pattern element 33RP is composed of a main line Lm and a sub-line Ls. At this time, in a plan view facing the sensing surface 33S, two driving electrode lines 41 adjacent to each other in the second direction D2 and two sensing electrode lines 51 adjacent to each other in the first direction D1 are formed.

The auxiliary line La of the reference pattern element 33RP may be sufficient.
設定於四個輔助線區域K的每一者之構成,亦可依各電極線間隙V為相同,亦可相異。在設定於四個輔助線區域K的每一者之輔助線的構成是依各電極線間隙V相異的構成中,由於輔助線的構成不會在各電極線間隙V重複,所以這樣的輔助線不會包含於基準圖案要素31RP、33RP。 The configuration of each of the four auxiliary line regions K may be the same or different depending on the electrode line gap V. In the configuration in which the auxiliary lines set in each of the four auxiliary line regions K are different according to the electrode line gaps V, since the configuration of the auxiliary lines does not repeat in each electrode line gap V, such an auxiliary line Lines are not included in the reference pattern elements 31RP and 33RP.

在與感測面33S對向的平面視圖中,在驅動虛擬部31DD中,除了電極部間隙45以外其餘的部分係與感測電容電極部33SPa面對面。因此,電極部間隙45係在第2方向D2形成於驅動電容電極部31DPa和感測電容電極部33SPa之間的間隙。 In a plan view opposite to the sensing surface 33S, in the driving dummy portion 31DD, the rest except the electrode portion gap 45 faces the sensing capacitor electrode portion 33SPa. Therefore, the electrode portion gap 45 is a gap formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa in the second direction D2.
位於電極部間隙45之驅動虛擬線42的每一者,係藉由例如位於驅動電極線41和驅動虛擬線42之間的電極線間隙46,而與驅動電極線41分離。位於電極部間隙45的驅動虛擬線42進一步藉由位於驅動虛擬 部31DD內部的虛擬線間隙47,而與驅動虛擬線42的一部分分離。亦可省略虛擬線間隙47。 Each of the driving dummy lines 42 located in the electrode portion gap 45 is separated from the driving electrode lines 41 by, for example, an electrode line gap 46 located between the driving electrode lines 41 and the driving dummy lines 42.

參照圖14,說明觸控感測器用電極的構成。圖14中,為了方便說明構成驅動電極之複數條驅動電極線的配置、及構成感測電極之複數條感測電極線的配置,而將驅動電極線的線寬及感測電極線的線寬誇大顯示。 The configuration of an electrode for a touch sensor will be described with reference to FIG. 14.

如圖14所示,一個感測電極33SP具備有沿第2方向D2排列的複數個感測電容電極部33SPa、和連接相互相鄰的兩個感測電容電極部33SPa之間的感測連接部33SPb。複數個感測電極33SP係沿第1方向D1排列。 As shown in FIG. 14, one sensing electrode 33SP includes a plurality of sensing capacitor electrode portions 33SPa arranged along the second direction D2 and a sensing connection portion connecting two sensing capacitor electrode portions 33SPa adjacent to each other. 33SPb. The plurality of sensing electrodes 33SP are arranged along the first direction D1.
在第1方向D1,電極部間隙55係位於相互相鄰的兩個感測電容電極部33SPa之間。電極部間隙55係沿著感測電容電極部33SPa之第1方向D1的外緣延伸。在電極部間隙55的每一者,設有屬感測虛擬部33SD的一部分的複數條感測虛擬線52。 In the first direction D1, the electrode portion gap 55 is located between two sensing capacitor electrode portions 33SPa adjacent to each other. The electrode portion gap 55 extends along the outer edge of the first direction D1 of the sensing capacitor electrode portion 33SPa. In each of the electrode portion gaps 55, a plurality of sensing virtual lines 52 that are part of the sensing dummy portion 33SD are provided.
在與感測面33S對向的平面視圖中,於感測虛擬部33SD中,除了電極部間隙55以外其餘的部分係與驅動電容電極部31DPa面對面。因此,電極部間隙55係在第1方向D1形成於感測電容電極部33SPa和驅動電容電極部31DPa之間的間隙。 In a plan view opposite to the sensing surface 33S, in the sensing dummy portion 33SD, the rest except the electrode portion gap 55 faces the driving capacitor electrode portion 31DPa. Therefore, the electrode portion gap 55 is a gap formed between the sensing capacitor electrode portion 33SPa and the driving capacitor electrode portion 31DPa in the first direction D1.
位於電極部間隙55之感測虛擬線52的每一者,係藉由例如位於感測電極線51和感測虛擬線52之 間的電極線間隙56,而與感測電極線51分離。位於電極部間隙55的感測虛擬線52進一步藉由位於感測虛擬部33SD內部的虛擬線間隙57,而與感測虛擬線52的一部分分離。亦可省略虛擬線間隙57。 Each of the sensing virtual lines 52 located in the electrode portion gap 55 is formed by, for example, between the sensing electrode lines 51 and the sensing virtual lines 52. The electrode line gap 56 is separated from the sensing electrode line 51. The sensing virtual line 52 located in the electrode part gap 55 is further separated from a part of the sensing virtual line 52 by a virtual line gap 57 located inside the sensing virtual part 33SD. The virtual line gap 57 may be omitted.
在觸控感測器用電極21中,在與感測面33S對向的平面視圖中,驅動電容電極部31DPa係與感測虛擬部33SD中除了電極部間隙55以外其餘的部分對向,感測電容電極部33SPa係與驅動虛擬部31DD中除了電極部間隙45以外其餘的部分對向。 In the touch sensor electrode 21, in a plan view facing the sensing surface 33S, the driving capacitor electrode portion 31DPa is opposed to the rest of the sensing virtual portion 33SD except the electrode portion gap 55, and senses The capacitor electrode portion 33SPa is opposed to the rest of the driving dummy portion 31DD except for the electrode portion gap 45.
因此,在與感測面33S對向的平面視圖中,在第2方向D2上相互相鄰的驅動電容電極部31DPa和感測電容電極部33SPa之間,形成有驅動面31S中的電極部間隙45和感測面33S中的電極部間隙55。因此,在與感測面33S對向的平面視圖中,相互相鄰的驅動電容電極部31DPa及感測電容電極部33SPa係在第1方向D1上相互分離兩個電極部間隙45、55的量,同時在第2方向D2上相互分離兩個電極部間隙45、55的量。 Therefore, in a plan view facing the sensing surface 33S, an electrode portion gap in the driving surface 31S is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa adjacent to each other in the second direction D2. 45 and the electrode portion gap 55 in the sensing surface 33S. Therefore, in a plan view facing the sensing surface 33S, the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa adjacent to each other are separated from each other by the amount of the gap 45, 55 between the two electrode portions in the first direction D1. , The two electrode portion gaps 45 and 55 are separated from each other in the second direction D2 at the same time.
在觸控感測器用電極21中,在驅動面31S,於驅動電容電極部31DPa和感測電容電極部33SPa之間形成有電極部間隙45,在感測面33S,於驅動電容電極部31DPa和感測電容電極部33SPa之間形成有電極部間隙55。 In the touch sensor electrode 21, an electrode portion gap 45 is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33SPa on the driving surface 31S, and the driving capacitor electrode portion 31DPa and the driving surface electrode 31DPa are formed on the sensing surface 33S. An electrode portion gap 55 is formed between the sensing capacitor electrode portions 33SPa.
因此,形成於驅動電容電極部31DPa和感測電容電極部33Spa之間的電場,容易受到來自透明介電 體基板33外側的影響。因此,檢測手指相對於觸控感測器用電極21的位置的精確度會提高。 Therefore, the electric field formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa is easily affected by the transparent dielectric material. Influence of the outside of the body substrate 33. Therefore, the accuracy of detecting the position of the finger with respect to the touch sensor electrode 21 is improved.
再者,驅動虛擬部31DD的一部分係位在驅動面31S的電極部間隙45,且感測虛擬部33SD係位在感測面33S的電極部間隙55。因此,即便是在觸控感測器用電極21形成電極部間隙的構成,也可抑制驅動電極31DP和感測電極33SP被辨識為各別的構造體。 Furthermore, a part of the driving dummy portion 31DD is located at the electrode portion gap 45 of the driving surface 31S, and the sensing dummy portion 33SD is located at the electrode portion gap 55 of the sensing surface 33S. Therefore, even in a configuration in which an electrode portion gap is formed in the touch sensor electrode 21, it is possible to suppress the drive electrode 31DP and the sense electrode 33SP from being recognized as separate structures.
又,在驅動面31S,於驅動電容電極部31DPa和感測電容電極部33Spa之間形成有電極部間隙45,在感測面33S,於驅動電容電極部31DPa和感測電容電極部33Spa之間形成有電極部間隙55。 Further, on the driving surface 31S, an electrode portion gap 45 is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa, and on the sensing surface 33S between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa. An electrode portion gap 55 is formed.
因此,與驅動電容電極部31DPa的一部分位於電極部間隙45,且感測電容電極部33SPa的一部分位於電極部間隙55的構成相比,驅動電容電極部31DPa和感測電容電極部33Spa之間的靜電電容的大小會改變。藉此,可使驅動電容電極部31DPa和感測電容電極部33Spa之間的靜電電容,配合連接觸控感測器用電極21的控制部36的規格而改變。 Therefore, compared with a configuration in which a part of the driving capacitor electrode portion 31DPa is located in the electrode portion gap 45 and a portion of the sensing capacitor electrode portion 33SPa is located in the electrode portion gap 55, the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa The capacitance will change. Thereby, the electrostatic capacitance between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa can be changed according to the specifications of the control portion 36 connected to the touch sensor electrode 21.
且,僅藉由在驅動面31S中設定電極線間隙46的位置,且在感測面33S中設定電極線間隙56的位置,即可改變驅動電極31DP和感測電極33SP之間的靜電電容。因此,可在不會迫使觸控感測器用電極21所具備之驅動電極31DP的設計之大幅的變更、或感測電極33SP的設計之大幅的變更之情況下,改變驅動電極31DP和感測電極33SP之間的靜電電容。 Moreover, by setting the position of the electrode line gap 46 in the driving surface 31S and the position of the electrode line gap 56 in the sensing surface 33S, the electrostatic capacitance between the driving electrode 31DP and the sensing electrode 33SP can be changed. Therefore, the driving electrode 31DP and the sensing electrode can be changed without forcing a large change in the design of the driving electrode 31DP included in the touch sensor electrode 21 or a large change in the design of the sensing electrode 33SP. Electrostatic capacitance between 33SP.

(7)在與感測面33S對向的平面視圖中,由於在驅動電容電極部31DPa和感測電容電極部33Spa之間形成電極部間隙45,所以檢測手指相對於觸控感測器用電極21的位置之精確度會提高。且,由於驅動虛擬部31DD的一部分位在複數個電極部間隙45,故即便是形成此種電極部間隙45的構成,也可抑制驅動電極31DP和感測電極33SP被辨識為各別的構造體。 (7) In a plan view facing the sensing surface 33S, since the electrode portion gap 45 is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa, the detection finger is detected with respect to the touch sensor electrode 21 The accuracy of the location will be improved. In addition, since a part of the driving dummy portion 31DD is located in the plurality of electrode portion gaps 45, even if such an electrode portion gap 45 is formed, it is possible to prevent the driving electrode 31DP and the sensing electrode 33SP from being recognized as separate structures. .
(8)在與感測面33S對向的平面視圖中,由於在驅動電容電極部31DPa和感測電容電極部33Spa之間形成電極部間隙55,故檢測手指相對於觸控感測器用電極21的位置的精確度會提高。且,由於感測虛擬部33SD的一部分位在複數個電極部間隙55,故即便形成此種電極部間隙55的構成,也可抑制驅動電極31DP和感測電極33SP被辨識為各別的構造體。 (8) In a plan view facing the sensing surface 33S, since an electrode portion gap 55 is formed between the driving capacitor electrode portion 31DPa and the sensing capacitor electrode portion 33Spa, the detection of a finger with respect to the touch sensor electrode 21 The accuracy of the location will be improved. Furthermore, since a part of the sensing dummy portion 33SD is located in the plurality of electrode portion gaps 55, even if such a configuration of the electrode portion gaps 55 is formed, it is possible to prevent the driving electrodes 31DP and the sensing electrodes 33SP from being recognized as separate structures. .

亦即,與一個起點圖案要素31RPs相連的複數個基準圖案要素31RP,係朝向第2方向D2的位置相差線間寬度GL的1倍的量之其他起點圖案要素31RPs延伸。因此,在單位區域21U中,構成驅動配線群的配線的每一者,係從起點圖案要素31RPs朝向在第1方向D1相互相鄰的單位區域21U的起點圖案要素31RPs,延伸成傾斜線間寬度GL的1倍的量。 That is, the plurality of reference pattern elements 31RP connected to one starting pattern element 31RPs extend toward the other starting pattern elements 31RPs by an amount that is twice as large as the line-to-line width GL by the position difference in the second direction D2. Therefore, in the unit area 21U, each of the wirings constituting the drive wiring group is extended from the starting point pattern element 31RPs toward the starting point pattern element 31RPs of the unit area 21U adjacent to each other in the first direction D1, and is extended to have an inclined line width 1x the amount of GL.
構成驅動配線群的驅動電極線61及驅動圖案群63的每一者,係從各起點圖案要素31RPs沿著相互平行的方向延伸。因此,2條驅動電極線61之間的距離及驅動電極線61和驅動圖案群63之間的距離係保持為線間寬度GL。 Each of the driving electrode line 61 and the driving pattern group 63 constituting the driving wiring group extends from the starting point pattern elements 31RPs in parallel directions. Therefore, the distance between the two driving electrode lines 61 and the distance between the driving electrode lines 61 and the driving pattern group 63 are maintained at the line-to-line width GL.

And, with a starting pattern element The plurality of reference pattern elements 33RP connected to 33RPs extend in a position in the first direction D1 toward the starting pattern element 33RPs of an amount that is twice the width GL of the phase difference line. The starting point pattern element 33RPs in the unit area 21U of the sensing surface 33S is an example of a second starting point pattern element.
參照圖18,說明觸控感測器用電極的構成。圖18中,為了方面說明構成驅動電極31DP之複數條驅動電極線的配置、和構成感測電極33SP之複數條感測電極線的配置,而將驅動電極線的線寬和感測電極線的線寬誇大顯示。 The configuration of an electrode for a touch sensor will be described with reference to FIG. 18. In FIG. 18, in order to explain the arrangement of the plurality of driving electrode lines constituting the driving electrode 31DP and the arrangement of the plurality of sensing electrode lines constituting the sensing electrode 33SP, the line width of the driving electrode line and the Exaggerated line width display.
如圖18所示,在觸控感測器用電極21中,在與感測面33S對向的平面視圖,驅動電容電極部31DPa與感測虛擬部33SD重疊,感測電容電極部33SPa與驅動虛擬部31DD重疊,且驅動連接部31DPb與感測連接部33SPb重疊。藉此,形成具有正方形形狀之單位格子連續的一個格子圖案。 As shown in FIG. 18, in the touch sensor electrode 21, in a plan view facing the sensing surface 33S, the driving capacitor electrode portion 31DPa overlaps the sensing dummy portion 33SD, and the sensing capacitor electrode portion 33SPa and the driving dummy The portion 31DD overlaps, and the driving connection portion 31DPb overlaps the sensing connection portion 33SPb. Thereby, a lattice pattern in which a unit lattice having a square shape is continuous is formed.
在驅動面31S的單位區域21U的各個中,與一個起點圖案要素31RPs相連的複數個基準圖案要素31RP,其在第2方向D2的位置係朝向相差線間寬度GL的1倍的量之起點圖案要素31RPs延伸。又,在感測面33S的單位區域21U的各個中,與一個起點圖案要素33RPs相連的複數個基準圖案要素33RP,其在第1方向D1的位置係朝向相差線間寬度GL的1倍的量之起點圖案要素33RPs延伸。 In each of the unit areas 21U of the driving surface 31S, a plurality of reference pattern elements 31RP connected to one starting pattern element 31RPs has a position in the second direction D2 toward the starting pattern of an amount that is twice the width GL of the phase difference Element 31RPs is extended. Further, in each of the unit areas 21U of the sensing surface 33S, the plurality of reference pattern elements 33RP connected to one starting pattern element 33RPs are positioned in the first direction D1 toward an amount that is twice the width GL of the phase difference line. The starting point pattern element 33RPs extends.
因此,在觸控感測器用電極21所形成的格子圖案中連續的單位格子雖然包含第1實施形態的基準圖案要素31RP、33RP,但是構成單位格子的主線Lm和基準方向所形成的主線角度θ係與第1實施形態的觸控感測器用電極21相互不同。 Therefore, although the continuous unit grid in the grid pattern formed by the touch sensor electrodes 21 includes the reference pattern elements 31RP and 33RP of the first embodiment, the main line angle θ formed by the main line Lm and the reference direction constituting the unit grid is θ. This is different from the touch sensor electrode 21 of the first embodiment.
說明上述觸控感測器用電極的作用。 The function of the electrode for a touch sensor will be described.
本實施形態的觸控感測器用電極21係可藉由僅從第1實施形態的觸控感測器用電極21以如下的方式變更設計來形成。亦即,在構成驅動配線群的配線中,設定一個單位區域21U中的起點圖案要素31RPs之第2方向D2的位置。與各起點圖案要素31RPs相連之複數個基準圖案要素31RP延伸的方向,係變更為朝向在第2方向D2偏離線間寬度GL的n倍(n為1以上的整數)的量之其他起點圖案要素31RPs的方向。 The touch sensor electrode 21 according to this embodiment can be formed by changing the design only from the touch sensor electrode 21 according to the first embodiment as follows. That is, in the wiring constituting the driving wiring group, a position in the second direction D2 of the starting point pattern element 31RPs in one unit area 21U is set. The extending direction of the plurality of reference pattern elements 31RP connected to each of the starting pattern elements 31RPs is changed to another starting pattern element that is shifted by n times (n is an integer of 1 or more) from the line width GL in the second direction D2. 31RPs direction.
又,在構成感測配線群的配線中,設定一個單位區域21U中之起點圖案要素33RPs之第1方向D1的位置。且,與一個單位區域21U的起點圖案要素33RPs相連之複數個基準圖案要素33RP延伸的方向,係變更為朝向在第1方向D1偏離線間寬度GL的n倍(n為1以上的整數)的量之其他起點圖案要素33RPs的方向。且,在第1方向D1連續的複數個驅動配線群和在第2方向D2連續的複數個感測配線群的每一者,係以在與感測面33S對向的平面視圖中形成格子圖案的方式連接。 Moreover, in the wiring constituting the sensing wiring group, a position in the first direction D1 of the starting point pattern element 33RPs in one unit area 21U is set. In addition, the direction in which the plurality of reference pattern elements 33RP connected to the starting pattern element 33RPs of one unit area 21U extends is changed to n times (n is an integer of 1 or more) that deviates from the inter-line width GL in the first direction D1. The direction of the other starting point pattern elements 33RPs. Further, each of the plurality of driving wiring groups continuous in the first direction D1 and the plurality of sensing wiring groups continuous in the second direction D2 is formed in a grid pattern in a plan view facing the sensing surface 33S. Way to connect.
如上所述,既然獲得形成格子圖案的觸控感測器用電極21,就不需要大幅變更驅動面31S之驅動電極31DP及驅動虛擬部31DD的設計、及感測面33S之感測電極33SP及感測虛擬部33SD的設計的各者。 As described above, since the touch sensor electrodes 21 having a grid pattern are obtained, it is not necessary to significantly change the design of the driving electrode 31DP and the driving dummy portion 31DD of the driving surface 31S, and the sensing electrodes 33SP and sensing of the sensing surface 33S. Each of the designs of the virtual part 33SD was measured.
如以上說明,根據第3實施形態,可獲得以下的優點。 As described above, according to the third embodiment, the following advantages can be obtained.
(9)即便在變更構成格子圖案之複數個線段的各個所具有之相對於第1方向D1及第2方向D2的傾斜時,也會制定驅動電極線61及感測電極線71的位置作為包含基準圖案要素31RP、33RP的電極線。因此,可使設計驅動電極線61及感測電極線71的負荷變小。 (9) Even when the inclination with respect to the first direction D1 and the second direction D2 of each of the plurality of line segments constituting the lattice pattern is changed, the positions of the driving electrode line 61 and the sensing electrode line 71 are included as The electrode lines of the reference pattern elements 31RP and 33RP. Therefore, the load of designing the driving electrode line 61 and the sensing electrode line 71 can be reduced.

‧在驅動面31S的一個單位區域21U中,與第C配線31C的起點圖案要素31RPs相連的複數個基準圖案要素31RP,亦可朝向在第1方向D1相鄰的單位區域21U中的第A配線31A的起點圖案要素31RPs延伸。或者,與第D配線31D的起點圖案要素31RPs相連的複數個基準圖案要素31RP,亦可朝向在第1方向D1相鄰的單位區域21U中的第A配線31A的起點圖案要素31RPs延伸。 ‧ In one unit area 21U of the driving surface 31S, the plurality of reference pattern elements 31RP connected to the starting pattern element 31RPs of the Cth wiring 31C may also face the Ath wiring in the unit area 21U adjacent to the first direction D1. The starting pattern element 31RPs of 31A extends. Alternatively, the plurality of reference pattern elements 31RP connected to the starting pattern element 31RPs of the Dth wiring 31D may extend toward the starting pattern element 31RPs of the Ath wiring 31A in the unit area 21U adjacent to the first direction D1.
總之,與一個起點圖案要素31RPs相連的複數個基準圖案要素31RP,其在第2方向D2的位置只要朝向相差線間寬度GL的整數倍的量之起點圖案要素延 伸即可。在感測面33S的單位區域21U中,與各配線的起點圖案要素31RPs相連的複數個基準圖案要素31RP所延伸的方向,只要依據驅動面31S的單位區域21U來制定即可。即便是這樣的構成,也可獲得基於上述(9)的優點。 In short, a plurality of reference pattern elements 31RP connected to one starting pattern element 31RPs have their positions in the second direction D2 extended as long as the starting pattern elements are an integer multiple of the width GL between the phase difference lines. Just stretch it. In the unit area 21U of the sensing surface 33S, the direction in which the plurality of reference pattern elements 31RP connected to the starting pattern elements 31RPs of the wirings extend may be determined based on the unit area 21U of the driving surface 31S. Even with such a configuration, the advantages based on the above (9) can be obtained.

‧如圖19所示,在構成觸控面板20的觸控感測器用電極21中,亦可省略透明基板31及透明黏著層32。在此種構成中,在透明介電體基板33的面中,只要與顯示面板10對向的一個面被設定為驅動面31S,且驅動電極31DP位於驅動面31S即可。且,只要感測電極33SP位在透明介電體基板33中之與驅動面31S對向的面即可。 • As shown in FIG. 19, in the touch sensor electrode 21 constituting the touch panel 20, the transparent substrate 31 and the transparent adhesive layer 32 may be omitted. In this configuration, among the surfaces of the transparent dielectric substrate 33, one surface facing the display panel 10 may be set as the driving surface 31S, and the driving electrode 31DP may be positioned on the driving surface 31S. In addition, as long as the sensing electrode 33SP is located on the surface of the transparent dielectric substrate 33 that faces the driving surface 31S, the sensing electrode 33SP is located.
在這樣的構成中,驅動電極31DP係可藉由例如形成於驅動面31S之一個薄膜的圖案化而形成。 In such a configuration, the driving electrode 31DP can be formed by, for example, patterning a thin film formed on the driving surface 31S.
‧如圖20所示,在觸控面板20中,亦可從接近顯示面板10的構成要素,依序設置驅動電極31DP、透明基板31、透明黏著層32、透明介電體基板33、感測電極33SP、透明黏著層23、覆蓋層22。 ‧As shown in FIG. 20, in the touch panel 20, the driving electrodes 31DP, the transparent substrate 31, the transparent adhesive layer 32, the transparent dielectric substrate 33, and the sensor can be sequentially arranged from the constituent elements close to the display panel 10.

在這樣的構成中,例如,驅動電極31DP形成於屬透明基板31的一個面之驅動面31S,感測電極33SP形成於屬透明介電體基板33的一個面之感測面33S。且,透明基板31中之與驅動面31S對向的面、和透明介電體基板33中之與感測面33S對應的面係藉由透明黏著層32黏著。 In such a configuration, for example, the driving electrode 31DP is formed on the driving surface 31S belonging to one surface of the transparent substrate 31, and the sensing electrode 33SP is formed on the sensing surface 33S belonging to one surface of the transparent dielectric substrate 33. The transparent substrate 31 faces the driving surface 31S, and the transparent dielectric substrate 33 has a surface corresponding to the sensing surface 33S, which is adhered by the transparent adhesive layer 32.
‧觸控面板20和顯示面板10亦可不是個別地形成,觸控面板20亦可與顯示面板10形成一體。在這樣的構成中,例如,亦可作成在觸控感測器用電極21中,複數個驅動電極31DP位於TFT層13,另一方面複數個感測電極33SP位於彩色濾光片基板16和上側偏光板17之間的in-cell構成。或者,亦可為觸控感測器用電極21位於彩色濾光片基板16和上側偏光板17之間的on-cell構成。 • The touch panel 20 and the display panel 10 may not be formed separately, and the touch panel 20 may be formed integrally with the display panel 10. In such a configuration, for example, in the touch sensor electrode 21, a plurality of driving electrodes 31DP may be located on the TFT layer 13, and a plurality of sensing electrodes 33SP may be located on the color filter substrate 16 and the upper polarized light.
